Dazzling digital cameras

From Nasa Techbriefs:

"DIGITAL CAMERA DISRUPTER
A prototype device developed by a team at the Interactive and
Intelligent Computer Division at Georgia Tech (Atlanta, GA) neutralizes
a digital camera by dazzling it. Using off-the-shelf technology, the
device scans for camera-shaped objects and a digital camera's CCD. Once
a target is identified, the device beams a ray of white light into the
CCD, flash-blinding the camera. Researchers note that the device could
have applications in high-security areas as an anti-espionage tactic or
in movie theaters to prevent piracy.

The prototype uses visible light and two cameras for scanning, but
developers envision the use of infrared technology and photo-detecting
transistors in the future.
